Red Hat Security Advisory

 

Synopsis: Critical: java-1.8.0-openjdk security update

Advisory ID: RHSA-2016:0650-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0650.html

Issue date: 2016-04-20

CVE Names: CVE-2016-0686 CVE-2016-0687 CVE-2016-0695

CVE-2016-3425 CVE-2016-3426 CVE-2016-3427

=====================================================================

 

1. Summary:

 

An update for java-1.8.0-openjdk is now available for Red Hat Enterprise

Linux 7.

 

Red Hat Product Security has rated this update as having a security impact

of Critical. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available for each vulnerability from

the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Client (v. 7) - x86_64

Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64

Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64

Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64

Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Server Optional (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 7) - x86_64

Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, x86_64

 

3. Description:

 

The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime

Environment and the OpenJDK 8 Java Software Development Kit.

 

Security Fix(es):

 

* Multiple flaws were discovered in the Serialization and Hotspot

components in OpenJDK. An untrusted Java application or applet could use

these flaws to completely bypass Java sandbox restrictions. (CVE-2016-0686,

CVE-2016-0687)

 

* It was discovered that the RMI server implementation in the JMX component

in OpenJDK did not restrict which classes can be deserialized when

deserializing authentication credentials. A remote, unauthenticated

attacker able to connect to a JMX port could possibly use this flaw to

trigger deserialization flaws. (CVE-2016-3427)

 

* It was discovered that the JAXP component in OpenJDK failed to properly

handle Unicode surrogate pairs used as part of the XML attribute values.

Specially crafted XML input could cause a Java application to use an

excessive amount of memory when parsed. (CVE-2016-3425)

 

* It was discovered that the GCM (Galois/Counter Mode) implementation in

the JCE component in OpenJDK used a non-constant time comparison when

comparing GCM authentication tags. A remote attacker could possibly use

this flaw to determine the value of the authentication tag. (CVE-2016-3426)

 

* It was discovered that the Security component in OpenJDK failed to check

the digest algorithm strength when generating DSA signatures. The use of a

digest weaker than the key strength could lead to the generation of

signatures that were weaker than expected. (CVE-2016-0695)

 

Note: If the web browser plug-in provided by the icedtea-web package was

installed, the issues exposed via Java applets could have been exploited

without user interaction if a user visited a malicious website.

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

All running instances of OpenJDK Java must be restarted for this update to

take effect.

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

1327743 - CVE-2016-0686 OpenJDK: insufficient thread consistency checks in ObjectInputStream (Serialization, 8129952)

1327749 - CVE-2016-0687 OpenJDK: insufficient byte type checks (Hotspot, 8132051)

1328022 - CVE-2016-0695 OpenJDK: insufficient DSA key parameters checks (Security, 8138593)

1328040 - CVE-2016-3425 OpenJDK: incorrect handling of surrogate pairs in XML attribute values (JAXP, 8143167)

1328059 - CVE-2016-3426 OpenJDK: non-constant time GCM authentication tag comparison (JCE, 8143945)

1328210 - CVE-2016-3427 OpenJDK: unrestricted deserialization of authentication credentials (JMX, 8144430)
